Sorry I haven't posted in a while, but inspiration strikes when inspiration strikes.

Say, what if, when Lance was born, he was born at the School. Part of the Avian Program, he left with Jeb at a young age and was separated from the rest of the flock. His family found him and raised him as their own. This leads up to the start of season one. When does Voltron find out about their blue friend? How do they find out? And what are their reactions?
